Hi, as my Acer Laptop only has a via ac97 chipset and one mono (mic) input and one stereo (headphone) output, I consider getting some additional hardware. I have two USB ports and a PCMCIA Card slot. Which one is better to use as a sound input/output? I mean sound quality and latency. I am running ecasound on top of alsa 0.9.2 and the 2.5.66 kernel. Any suggestions for a particular card/device/setup? Thanks a lot. Jan
